CN2786722Y - Multifunctional anti-kicking alarm - Google Patents

Abstract

The utility model relates to a multifunctional anti-kicking alarm which is composed of a transmitter and a receiver, wherein the transmitter is formed by that two parallel anti-kicking monitoring switches are serially connected to a power supply circuit of an LC sine-wave oscillator; a signal receiving circuit, output sound, a change-over switch S and a toy with 2.4-6V service voltage are combined to be arranged in the receiver. When the utility model is used, fixed holes of the anti-kicking monitoring switches are fixed on the left corner and the right corner of a pillow for children, a quilt is clamped by the front end, and the quilt is connected with the pillow through the anti-kicking monitoring switches, which causes the quilt to be not easy to kick away; when the quilt is kick away, wireless signals can be emitted by the transmitter and the wireless signals are transported by the receiver to enable the receiver to emit sound to remind people who nurse. Because the receiver is combined with the toy, the utility model can be used as a common toy at mean time.

Description

Multi-functional anti-quilt kicking alarm

Technical field

The utility model relates to a kind of multi-functional anti-quilt kicking alarm.

Background technology

At present, traditional anti-play product be by slide fastener or rope strap-on prevent to play by, not only comfort level is not good enough, cause child's sleep quality bad easily, and cost is higher, purposes is single; Any play of relatively economical by the warning product, according to the difference of function design also each defectiveness, what have wakes child easily up, and tender is difficult for hearing, the meeting that has is failed to report wrong report according to child's sleeping position, and can not prevent child play by, do not reach the desirable anti-warning effect of playing yet.

Summary of the invention

The utility model is the deficiency that exists in the above-mentioned prior art in order to solve, and provides a kind of easy to use, need not directly contact with human body to realize anti-function of playing warning.

To achieve these goals, the utility model adopts following scheme:

This multi-functional anti-quilt kicking alarm is made up of transmitter and receiver, transmitter is that the anti-monitoring switch of playing of two parallel connections of series connection on the power circuit of LC sine-wave oscillator is formed, receiver is by signal receiving circuit, the output sound, switch S and and the toy combination of working voltage 2.4～6V, be contained in its inner composition.

The anti-monitoring switch of playing is to load onto long conducting strip 2 in one of them of two intermediate plates 4, another is contained in two short conducting strips 1 that are separated from each other, one of them short-range missile sheet is connected with the positive pole of light-emitting diodes light 3, and 4 pairs of two intermediate plates of the accessory that installs are folded, jump ring 5 on the card and forming; Receiver is by the series connection of output sound and signal receiving circuit, again with the parallel connection of toy power supply, forms playing to be switched by warning function and play function by switch.

The utility model can be played by phenomenon child certain effect that prevents, and kicks open by the period of the day from 11 p.m. to 1 a.m and realize and can tender can in time be handled to the function of tender room radio alarming, avoids child because of kicking open the disease that quilt catches cold and causes.

Among the figure: 1 is short conducting strip, and 2 are long conducting strip, and 3 is light emitting diode, and 4 is intermediate plate, and 5 is jump ring, and 6 is fixed orifice, and 7 is transmitter, and 8 is to prevent playing the monitoring switch, and 9 is pillow, and 10 is quilt.

Embodiment

Shown in Fig. 3,4: the utility model is made up of transmitter and receiver, and transmitter is by two anti-monitoring switches, LC sine-wave oscillator played, power switch S01 and Voltaic battery are formed, and receiver is made a noise and rung assembling device by signal receiver, toy, switch and 2.4～6 volts of power supplys are formed.

As shown in Figure 1: the anti-monitoring switch of playing is to load onto long conducting strip 2 in one of them of two intermediate plates 4, another is contained in two short conducting strips 1 that are separated from each other, one of them short-range missile sheet is connected with the positive pole of light-emitting diodes light 3,4 pairs of two intermediate plates of the accessory that installs are folded, jump ring 5 on the card and forming, another short conducting strip is the anti-input end of playing the monitoring switch, the negative pole of light emitting diode is its output terminal, the effect of light emitting diode is step-down and signal indication, simultaneously can save electric energy, remind the user at time spent powered-down not.

As shown in Figure 3: 9 volts of power supplys are monitored K switch 1, VL1 through anti-the playing of two parallel connections of power switch S01 control, K2, VL2, and output provides about 7 volts voltage for the LC sine-wave oscillator through light emitting diode VL1, VL2 step-down.

As shown in Figure 4: power supply is given to signal receiving circuit or the toy power supply through switch S, and the power output end of signal receiving circuit is given to make a noise and rung the device power supply.

As shown in Figure 2: the anti-fixed orifice of playing on the monitoring switch 86 with transmitter 7, one-time fix pillow 9 right corner child, front end is clamped quilt 10, and this will be connected quilt by the anti-monitoring switch of playing with pillow, quilt can not kicked open easily.

As shown in Figure 4: the switch of receiver is placed an end of signal receiving circuit, and place it in outside child's the bedroom or the room of tender, in order to avoid wake child up.

Shown in Fig. 5,6: when quilt is kicked open, the monitoring switch of corresponding sides and quilt break away from, K1 or K2 closure, VL1 or VL2 are bright, the starting of oscillation of LC oscillation circuit, send sine wave signal, amplify and transmission through V01, receiver is amplified through V1 by the local oscillator detection after receiving signal, supplies with CMOS integrated gate circuit IC1, the 8 pin output high level of IC1, V3, V2 conducting, the IC2 power supply that giving makes a noise rings device, the 3 pin output audio signals of IC2, amplify supply loudspeaker BL through V4 and send sound, remind tender to cover quilt for it.

When not doing to prevent playing the warning use, the switch S of receiver can be placed play function, can make conventional toy this moment and use, supply child's amusement and study (study is meant the alarm of making outward appearance with puzzle-type toy).
